Not only birds and animals can be trapped in a cage.
Feng Weixu, who had lost his memory, met Nian Shuling in Hejin Park and was taken home by him. As they got along, Feng Weixu, who gradually fell in love with Nian Shuling, realized that she was just a "substitute".
"Nian Shuling, let me go. In the past, I was willing, but now, I know I don't deserve it." When she was about to leave, she realized how strong the "cage" Nian Shuling had built was. She had no choice but to agree to Nian Shuling's request to stay for another hundred days.
"Why call me Wei Xu?"
"For (Wei) you alone, I promise (Xu) a lifetime."
In the end, as her past memories were recovered, she gradually regained her past true self.
